The bolt moves in-line with the chamber, lever-action or not.

Any extractor which grabs one side of the rimmed case will create an unequal force during extraction, on the rim.

The rim is as strong as the material and dimensions allow.

Maximum loads will stretch the case ahead of the "web" area. As I understand, this is rare in most pistol calibers, but with .44 Mag and up it is possible.

However, this area of the case isn't subject to "torque" during extraction.

Can you explain the torque concern in a little more detail?
